The anti-snapback rollers are made of a new, proprietary material that has the ability to accommodate changes in paper thickness and ribbon count without affecting the amount of pull that the rollers provide to the web. This means that there is no need to adjust ASB settings as part of a job or version change, saving time on every job. It removes the remaining folder adjustment when changing over to new paper stock or when changing the number of ribbons over the former.
Only available on folders with Zero-slip nips.
